Application filed April 6, 1899. erial No. 711,944. (No model.)

[b all whom it-may concern:

Be it known that we, THEODORE A. FROEH- LICH and HELEN B. FROEHLIOH, ofthe city of New York, borough of Manhattan, in the county and State ofNew York, have invented a new and Improved Weather-Signal Indica: tor,of which the following is a full, clear, and exact description.

The object of the invention is to provide a to new and improvedweather-signal indicator, more especially designed for use in schoolsand arranged to permit of conveniently displaying weather-signalsaccording to official reports received as to the state of the weather,

the indicator serving principally to enable a teacher to teachmeteorological conditions.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then point- 2:) edout in the claims. I

I A practical embodiment of our invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement. Fig. 2 is a sectionalplan view of the same on the line 2 2 in Fig. 1. Fig. 3 is an enlargedsectional side elevation of the post and support for the signal-flags.Fig. 4 is a sectional perspective view of partof the base, and Fig. 5 isan enlarged sectional side elevationof part of the post with asignal-flag secured thereon.

The improved indicator is provided with a base A, adapted to be set on atable or other suitable support, and on said base is erected a post B,supporting at its upper end compasspoints 0, and aweather-vane D forindicating the direction of the wind on the compasspoints 0, locatedbelow the vane. On one side of the post B is arranged avertically-extending rod E, formed at its lower end into a coil E,terminating in a bolt E secured in the post B near the base A, as isplainly illustrated in the drawings. The upper free end of the rod E isadapted to be engaged bya loop F, held on the upper end of the post B tohold the rod normally in a vertical position to allow the operator todisengage the loop from the rod to permit of fastening a series ofsignal-flags H H H on said rod, as shown in appearance of the device andstimulatingpatriotic sentiment. The several flags are made of stiffmaterial-such as cardboard, sheet metal, or the like-and said flags H HH are painted and shaped similarly to the signal-flags used by theUnited States Weather Bureau to indicate meteorological conditions.

By the arrangement described the teacher is enabled to readily unlockthe upper end of the rod E and then conveniently remove the severalflags I, H, H, and H and place other signal-flags on said rod E,according to the prevalent weather conditions as reported by the UnitedStates Weather Bureau. 1

The base A is preferably provided with beveled sides A, containingindicators K, L, N, and O, of which the indicator K consists of agraduated scale K, representing inches and subdivisions for barometricalpressure, a pointer]? being fitted to slide on a guideway Q for pointingon the corresponding graduation'on the scale K and indicating theprevalent barometrical pressure. The indicator L is for indicatingtemperature and consists'of a graduation L, having degrees of heat andon which indicates a pointer P, likewise held to slide on a guideway Q.The indicator N is for indicating the force of the prevalent wind and isprovided with the names of the different winds, and which names areindicated bya pointer Pfifitted to slide on a guideway Q The otherindicator 0 is for indicating the condition of the clouds and isprovided with the names of the different kinds of clouds and a pointer Pfitted to slide'on a guideway Q By the operator shifting the severalpointers P, P, P and P on their corresponding guideways it is possibleto indicate barometric pressure at a given hour, the temperature, theforce of the wind, and the condition of the clouds for a certain time.

If desired, the post B maybe provided with sets of apertures B on theside opposite to that on which the rod E extends, and these aperturesare adapted to be engaged by angular hooks J, formed on auxiliarysignalflags J for displaying the condition of the weather for theprevious day to afford oppor tunities of drill on the different signalsindicating various conditions of the Weather, so as to bring the flags HFYI-1 in view with the flags J for indicating the changing conditions ofthe weather from one day to another.

From the foregoing it will be seen that the device is very simple anddurable in construction, facilitates education in meteorologicalmatters, and enables teachers and scholars to readily change thesignal-flags from day to day, according to ofiicial weather reports.

Having thus fully described ourinvention, we claim as new and desire tosecure by Letters Patent 1. A weather-signal indicator, comprising abase, a post erected thereon, a rod permanently secured to one end ofsaid post and removably connected at its other end with said post, andsignal-flags having ears adapted to engage said rod and display theflags at right angles to the rod, substantially as shown and described.

2. A weather-signal indicator, comprising a base, a post erectedthereon, a rod permanently secured to one end of said post and removablyconnected at its other end with said post, signal-flags having earsadapted to engage said rod and display the flags at right angles to therod, and a collar adj ustably secured on said rod to support the flags,as set forth.

3. A Weathersignal indicator, provided with a post having apertures inits side, and signal-flags having angular hooks for engaging saidapertures and removably supporting said flags on the post, said flagsstanding at an angle to the post, substantially as shown and described.

4. A Weather-signal indicator comprising a rectangular base, a postsupported on said base and arranged for removably carrying signal-flagsand a manually-operated indicator fitted to slide in the base along eachside thereof and adapted to indicate atmospheric pressure, temperature,prevalent winds and the condition of the clouds, substantially as shownand described.

5. A weather-signal indicator comprising a base, a post supported onsaid base and formed with a longitudinally-extending series ofapertures, a rod permanently secured to one end of said post andremovably connected at its other end to said post, a set of signal-flagshaving ears adapted to fit around said rod, a collar adjustably secured011 said rod and engaging an ear to support the flags and a second setof signal-flags having angular hooks adapted to enter the apertures inthe post whereby two sets of flags may be simultaneously displayed toillustrate the weather indications of different days, as and for thepurpose set forth.
